Abstract

PROBLEM TO BE SOLVED: To remove volatile organic compounds, etc., produced from building material, etc., and clean the air conditioner, by providing the air cleaner with two filters which adsorb particulate matter and chemical matter, a matter detecting sensor, and a temperature sensor, and controlling the operation of a heat source, etc., based on the information of these sensors. SOLUTION: When the surface temperature of building materials comes to 25 deg.C or over by the heating operation of an air conditioner 10, volatile organic compounds, etc., come out into the room from the building materials. Here, the temperature sensor 20 detects the temperature within the room, and a control circuit 9 starts the operation of an air cleaner 7. A part of the air passes a suction port 1, and the particulate matter is removed by a charged filter 2, and for the air including chemical matter, a filter 3 adsorbs a very small quantity of chemical matter. Volatile organic chemical compounds, etc., are adsorbed with activated carbon. The air having gotten clean this way is returned from a jet 6 into the room. After passage of a certain time, the air cleaner 7 stops the operation. Moreover, a gas combustor 13 makes a part of the indoor air flowing in from the suction port 11 hot air.

However, the conventional baking-out technique as described above does not clearly specify how many room temperatures or building material temperatures are required, and it is necessary to maintain how long the temperature is maintained. There is no indication. For this reason, technology for baking out economically and effectively without affecting building materials has not been established yet. Further, as a method for removing VOCs generated by baking out, only a method using ventilation has been proposed.

At this time, the particulate matter is removed by the charging filter 2. Next, air containing a trace amount of the chemical substance is adsorbed by the filter 3. Volatile organic compounds (VOCs) and formaldehyde are adsorbed on activated carbon. NOx is adsorbed on the metal complex. The air thus cleaned is returned from the first outlet 6 into the room. The air purifier 7 that has been operating for a certain period of time stops operating.
